摘要An azetidine (AZT) containing compound, 3-azetidinyl propanol was synthesized from methyl acrylate with 3-amino-1-propanol in a four-step reaction. It was introduced into an isocyanate-terminated carboxylic acid containing polyurethane (PU) prepolymer as the end group. A single-component, AZT-terminated self-curable aqueous-based PU dispersion was obtained from the water dispersion process after it was neutralized with triethylamine. Its carboxylic groups served not only as the internal emulsifier stabilizing the aqueous PU dispersion but also as PU self-curing sites toward its AZT end groups via a ring-opening reaction. The curing reaction took place on drying and resulted in polymeric network structure formation among the polymers. The performance properties of this self-cured PU were evaluated in this study.
